My mate is breaking his A8 D3 and offered me his MFSW. I currently have the standard 4 spoke wheel and I wanted to use the airbag from that into his wheel (also 4 spoke). Will the A8 MFSW fit in my A4 and will it code ok to the car? My car has cruise control fitted from the factory so I think the control module should be ok, please could someone confirm? Would I need to get anything else?
